安装kalibr
参考

出现了C++17兼容性的问题，修改对应的CMAKELists，加上
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -w")
出现了一些opencv版本导致的编译问题，逐个去修改就好
遇到了一些python问题，参考
如果pip安装python-igraph失败就用apt-get insatll
error code: ImportError: dynamic module does not define module export function (PyInit_libnumpy_eigen)

运行双目bag中发生的错误
Cameras are not connected through mutual observations, please check the dataset. Maybe adjust the approx. sync. tolerance.
我调整了image topic的发布频率为20HZ（单目时用4HZ），注释一部分python代码，详细见github issue
